IMPROVEMENT IN PEGGlNG-MACHINES.

Specification forming part of Letters Patent No. 159,776, dated February16, 1875; application filed February 8, 1875.

OAsE D.

To all whom it may concern:

Be it known that I, BENJAMIN F. STURTE- VANT, of Boston, in the countyof Suffolk and State of Massachusetts, have invented Improvements inPegging-Machines, of which the following is a specification:

The invention relates to improvements in pegging-machines; and consistsin the combination with a peg-guiding channel or way in apegging-machine, and with a peg-driver, of rotating dies or compressingmechanism adapted to compress, consolidate, and sever pegs from apeg-strip on its way to the pegdriver; also, in the combination ofamechanism for cross-pointing a peg-strip with rotating dies orcompressing mechanism for compressing and severing pegs from a peg-striphaving a row of points partially formed by cutting across the strip,substantially as described.

Figure 1 is a side view of part of a peggingmachine, showing myimprovements. Fig. 2 is a partially vertical section. Fig. 3 is alongitudinal section through the compressing and severing mechanism, andFig. 4 is a view of pegs which may be produced. by this mechan- 1sm.

A is the frame of the pegging-machine, of ordinary or suitableconstruction, and provided with a peg-guiding channel or way, B, itleading to a peg-driver, O, of well-known form, and operated in anywell-known way. The peg-guiding channel or way is bounded by plates at a(t -Ct being adjustable to adapt the channel or way to a pegstrip of thedesired size. In the frame A is mounted a rotating shaft, 0, operatedfrom any suitable moving shaft or wheel. This shaft has a wormgear, (I,and a toothed wheel, al the former engaging a toothed wheel, 0, on theshaft 0 of the rotating compressing-die f, which is placed just oppositea second rotating compressingdie, f, on a shaft, g, the twocompressing-dies moving in unison by means of the toothed wheels g g onshafts e 9. These compressing-dies are shown as wheels, having formed intheir faces a series of depressions or cavities, h, each correspondingin shape to half of the peg to be made, or as shown in Fig. 2 and atFig. 4. It will be noticed in Fig. 2 that these dies are not outentirely across their faces, but a larger or projecting portion, 1', isleft at one end, to consolidate the pegs or solefastenin gs at one edgemore than at the center, to compress the peg more at the edge than atthe center, to form consolidated points, or

points which are formed by the compression of the substance of the wood.The toothed wheel 61 engages. a toothed wheel, 6?, on a shaft, j,supporting the cross-pointer k, which is a wheel or cutter with a seriesof teeth, I. These teeth 1 of the cross-pointer move rapidly andcross-point the strip or notch the edge of the strip crosswise, halfforming points or forming wedge-shaped points standing across the strip.Shaft j also carries a screw, m, which engages the notches so formed inthe strip and feeds the strip forward to the action of thecompressing-dies f f. When the strip reaches these dies the points arehalf-formed; then the strip, as it passes between the dies, is acted onto compress the sides of the wood sufficiently hard to cause the wood tofill the spaces in the dies. The ribs 0 between the cavities h meet, ornearly so, to sever the pegs from the strip, and the part iof the diesacts on the half-formed point and finishes it. The dies compress andseparate the strip into pegs, and deliver the individual pegs 1) intothe pegguiding channel or way.

I do not desire to limit myself to providing the dies with cavities ofexactly the form shown, as the particular form of the cavities may bechanged without departing from my invention. The dies move the distanceof one cavity at each rotation of the shaft 0, or of the pegging machineshaft. The cross pointer and dies might be used independently of apegging-machine.

Having described my invention, I claim 1. The combination, with thepeg-guiding channel or way of a pegging-machine, of rotating,compressing, and severing dies, having cavities to receive and mold orcompress and sever pegs, substantially as described.

2. The combination of a cross-pointing mechanism with compressing-dies,substantially as described, to compress the body of the peg and thencompleting the point so formed by compressing the wood in opposition tothe direction of the edge of the partially-cut point between dies,substantially as described.

In testimony whereof Ihave signed myname to this specification in thepresence of two subscribing witnesses.
